The new Jaguar F-Type V8S, on paper, is a pretty stout automobile. It packs a supercharged V8 that makes 495 hp and 460 lb-ft of torque. It has an 8-speed automatic transmission, is dead sexy to look at and is the first real Jaguar performer in quite some time. However before you run out and spend $100k, you may want to consider that its rivals, the Porsche 911S Convertible and the Aston Martin V8 Vantage Roadster are also out there roaming the streets. Chris Harris recently got these three together to see which one was King of the high performer drop-tops.
